Some effects of raindrops and surface‐flow on soil erosion and infiltration

This presentation summarizes the findings from a number of experiments in which the effects of raindrop‐impacts and the flow of surface‐water on soil‐erosion and infiltration were studied. Some implications drawn from this work are discussed. Many of the experiments were exploratory in nature, and many of the data have only qualitative significance. The effects of impact of raindrops and of surface‐flow on the surface‐soil will, among other things, depend on the kinetic energy of the water in motion. Energy factors in rainfall and runoff were controlled for these experiments, and some of the effects of variations in energy were observed.
